“…HS-SPME technique is widely used for extracting various kinds of chemicals. Among them, in-vial (in situ) derivatization is frequently used for haloacetic acids (HAAs) [21,23] and acetic acid [67], aldehyde compounds [25,124,165], phenoxy acid herbicides [68], phenolic pollutants [17,18,82,91,159], aliphatic amines [120,125], acaricide fenbutatin oxide (FBTO) [131], acetone [111], selective serotonin reuptake inhibitors (SSRIs) such as venlafaxine, fluvoxamine, fluoxetine, citalopram, and sertraline [97], and organometallic compounds such as organotin [29,31,86,87,127,128,138,139,160], organolead [31,86,89,160], and organomercury [31,128,129,140,160]. On-fiber in situ derivatization is used for analyzing chemicals such as aldehyde compounds [27,105,164], carbonyls compounds [28], and thiol compounds [171].…”

Solid-phase microextraction (SPME) is a solvent-free sample preparation technique using a fused-silica fiber coated with an appropriate stationary phase. Derivatization is often necessary to determine substances with poor chromatographic behavior, high reactivity, and/or volatility or thermal instability. SPME derivatization technique can be operated under different combined modes and may be influenced by factors such as sample matrix, SPME, derivatization, and desorption condition. Combined with derivatization, HS-SPME, DI-SPME, membrane-protected SPME, and in-tube SPME have been applied to the analysis of a vast amount of chemicals, i.e., aldehydes and acetone, amines, organic acids, phenolic compounds, pesticide, metal and organic metal species, and pharmaceutical and personal care products (PPCPs) in a wide range of environmental matrices, including air, water, soil, and sediment samples. This chapter reviews the mode and method development of the derivatization technique, the derivatization reagents, and reaction mechanism, as well as its applications in environmental analysis.

“…The determination of the species will be more useful than the determination of the total amount of tin because it gives accurate information about the tin's existence and toxicity. Gas chromatography methods have high separation power and are connected to very sensitive detectors such as mass spectrometry, flame photometer detector, and atomic spectrometry (Cai et al, 1993;Narasaki and Wang, 1998;Jiang and Liu, 2000). High-performance liquid chromatography (HPLC) has been used as a separation technique, coupled with element-sensitive detection systems, because conventional HPLC detectors give a poor response to OTC.…”

The use of antifouling paints in shipbuilding has led to a significant concentration of organotin compounds in the marine environment. Antifouling paints have become the main source of tributyltin and triphenyltin derivatives loaded into the sea. The toxicity of organotin compounds has been of great concern. High concentrations of organotin compounds are associated with growth abnormalities in mussels and oysters and have also resulted to the decline in their abundance. High concentration of organotin compounds have also been found in the tissues of marine mammals and its presence has been linked to mass mortalities of marine mammals. It causes imposex and calcification anomalities in mollusks. Seafood is thought to be a possible source of organotin compounds in human. Therefore, to evaluate the environmental distribution and fate of these compounds and to determine the effectives of legal provisions adopted by a number of countries, a variety of analytical methods have been developed for the speciation of organotin compounds in the environment. A detailed review of the toxicity and chemical speciation of organotin compounds is given.

“…The pH was adjusted to approximately 4.0 by addition of 1 to 2 ml of a sodium acetate/acetic acid buffer (0.2 M, pH 4). Good recoveries of TBT in water samples were achieved at pH 2 to 4 [31] and did not appear to depend on salinity [19]. Tubes were allowed to rest undisturbed for phase separation.…”

A poor understanding of tributyltin (TBT) sorption on sediments has hindered an accurate evaluation of its environmental fate. The present study determined TBT sorption by a freshwater sediment (BH) and a coastal marine sediment (TZ) as influenced by pH, salinity, and biochar (BC) amendment into TZ. The isotherms were essentially linear, with K(OC) values in the range of 10(4) to 10(5) L/kg. Tributyltin sorption at pH 3.56 and 8.00 occurred mainly via partitioning. It reached maxima at pH equal to its pK(a) (=6.25) because of added ion exchange. A salinity increase from 5 to 35 practical salinity units enhanced TBT sorption at pH 3.56 and 8.00 on TZ by approximately 30% and on BH by approximately 80%, ascribed to the salting-out effect that reduced the solubilities of tributyltin hydroxide (TBTOH) and tributyltin chloride (TBTCl). At pH 6.25, the same salinity increase reduced TBT sorption on TZ by approximately 20% but enhanced TBT sorption on BH by approximately 35%. This was attributed to the enhancing role of salting out and the reducing role of metal competition for ion exchange. Tributyltin was two orders of magnitude more effectively sorbed by BC than by total organic carbon of TZ, mainly because of the high level of surface area of the BC. Although BC affinity for TBT may be significantly diminished when present in TZ, it was considered to be the primary contributor to TBT sorption from water. Biochar may thus be used to immobilize TBT in sediment for potential remediation.
